| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

| Description | L-Hisidine is an essential amino acid for infants. L-Hisidine is an inhibitor of mitochondrial glutamine transport.In Vitro:L-histidine completely inhibits growth and its effect on viability is inversely related to FLO11 expression. L-histidine does not affect the viability of the Δflo11 and S288c strains. L-histidine dramatically decreases air-liquid biofilm formation and adhesion to polystyrene of the flor yeasts with no effect on the transcription level of the FLO11 gene. Moreover, L-histidine modifies the chitin and glycans content on the cell-wall of flor yeasts[1].In Vivo:L-histidine (100 mg/kg) completely inhibits the brain edema in thioacetamide-treated rats[2]. Histamine release stimulated by high K+ from the hypothalamus in the L-histidine diet group is 60% of that in the control group. However, the concentrations of other monoamines and their metabolites are not changed by the L-histidine diet. The open-field tests show that the L-histidine diet group spends a shorter amount of time in the central zone, and the light/dark box tests demonstrate that the L-histidine diet group spends a shorter amount of time in the light box, suggesting that the L-histidine diet induced anxiety-like behaviors[3].

Cisplatin-mediated selective hydrolytic cleavage of methionine-containing peptides with neighboring serine or histidine residues.[Pubmed:15522420]
J Inorg Biochem. 2004 Nov;98(11):1947-56.
The pH- and time-dependent reactions of the anticancer drug cisplatin, cis-[PtCl(2)(NH(3))(2)], with the peptides Ac-Gly-Met-Gly-OH, Ac-Ser-Met-OH and Ac-Met-His-OH (Gly=glycyl, Met=methionyl, Ser=seryl, His=histidyl) at 313 K have been investigated by high-performance liquid chromatography, nuclear magnetic resonance and mass spectrometry. In the major equimolar reaction pathway for Ac-Gly-Met-Gly-OH, rapid anchoring at the methionine sulphur (kappaS) is followed by successive metalations of the methionine N(M) and glycyl N(G1) amide nitrogens in N-terminal direction to afford bidentate kappa(2)S,N(M) and tridentate kappa(3)S, N(M),N(G1) complexes. Cleavage of acetic acid at the second upstream amide bond is observed after 10 h leading to slow formation of [Pt(H-Gly-MetH(-1)-Gly-OH-kappa(3)S,N(M),N(G1))(NH(3))](+) at pH<6. [Pt(H-Ser-MetH(-1)-OH-kappa(3)S,N(M),N(S))(NH(3))](+) results from an analogous cisplatin-mediated regioselective hydrolytic cleavage reaction for Ac-Ser-Met-OH in moderately acid solution (pH<4). After passing through a minimum at pH 4.4, the concentration of the cleavage product in the reaction mixture after 500 h increases steadily on raising the pH and release of acetic acid is effectively quantitative for 7pH9.5. A competing mechanism involving nucleophilic attack of the serine side chain on the acetyl function can be inferred for pH>6 by the HPLC detection of a second intermediate kappa(3)S,N(M),N(S) species. In striking contrast, the reaction of cisplatin with Ac-Met-His-OH leads to release of acetylmethionine and formation of a final histidine product cis-[PtCl(H-His-OH-kappa(2)N3,N(H)) (NH(3))](+) at pH<6 by a kappaS-->kappa(2)S, N3-->kappa(3)S, N(H),N3-->kappa(2)N3,N(H)(H-His-OH) pathway.
